SaaS · Artificial intelligence

Multichannel AI agent platform for customer service and sales

Challenge

Small businesses needed to answer customers all day on WhatsApp, Instagram, email and marketplaces, with answers grounded in their own catalog and rules.

Solution

A multi-company no-code platform, evolved from an open-source base: agents trained on each company's documents and catalog, a helpdesk with human approval, social media publishing, prospecting, campaigns and recurring billing.

Result

In production as a commercial SaaS, with dozens of automated background routines: catalog sync, follow-ups, SLA control and campaigns.

Tax compliance · Electronic documents

Electronic tax document platform integrated with SEFAZ

Challenge

Issue Brazil's new electronic Content Declaration (DC-e) for several companies, each with its own digital certificate, and let client systems issue it through an API.

Solution

A multi-company portal and API: XML built and validated against the official schema, digital signature, SEFAZ authorization, PDF document (DACE), Excel/PDF reports and public Swagger documentation, with separate QA and production environments.

Result

Documents authorized by SEFAZ, automatic certificate selection by the issuer's tax ID, and ongoing expansion to NF-e and Brazil's tax reform (IBS/CBS).

Services company · CRM & finance

White-label CRM with sales, finance and prospecting

Challenge

A services company needed its sales pipeline, margin-based proposals, finance and prospecting in one secure system, cheap to host and easy to brand for other companies.

Solution

A PHP and SQLite system with server-side authentication, Kanban sales pipeline, margin calculator with PDF proposals, finance, SDR prospecting and Excel contact import. White-label, one deployment per company.

Result

In production on low-cost hosting, with automated tests, backups and a repeatable deployment package.

Integration partners · IoT

IoT software platform for device management

Challenge

Systems integrators needed their own software layer to connect, monitor and manage field devices across their projects, without depending on a single manufacturer or technology.

Solution

A cloud platform that receives device data in real time over MQTT, edge middleware for fixed equipment, telemetry for handheld devices and Android apps for field operations. Hardware-agnostic and ready for technologies beyond RFID.

Result

A white-label platform delivered through integration partners, who take care of hardware, installation and the end-customer relationship. Already running in a pilot with RFID.

Software company · Monitoring & alerts

Faster delivery for a camera-based monitoring platform

Challenge

Speed up the evolution of a monitoring and alerting platform and ship new versions without interrupting customers.

Solution

Zero-downtime deployment pipeline, a hardware sizing guide for edge appliances in five tiers by camera count, and AI agents that work through the Jira backlog respecting dependencies between tickets.

Result

Releases without downtime, standardized hardware proposals for the sales team, and tickets handled automatically in the right order.

Security & transparency

Google Account sign-in and integrations

Some Gestrato-developed applications offer Google Sign-In so users can authenticate with their Google Accounts. With permission, these applications may receive basic profile information, such as name, email address, profile picture and Google Account identifier, for account management.

Google Sign-In alone does not grant access to Gmail messages, Drive files or Calendar events. Access to additional Google services requires separately requested permissions and user authorization.

Your Google data stays under your control.

You can review or revoke connected-app access through your Google Account. For information about how data is accessed, used, stored, shared and deleted, please read our policies.
